Dahlia plant named &#39;LODABALVIO&#39;

ABSTRACT

A new and distinct  Dahlia  cultivar named ‘LODABALVIO’ is disclosed, characterized by bright violet flower color and full and compact plant growth. The new variety is a  Dahlia , typically produced as an indoor ornamental plant.

LATIN NAME OF THE GENUS AND SPECIES

Dahlia hybrid.

VARIETY DENOMINATION

‘LODABALVIO’

BACKGROUND OF THE INVENTION

This application relates to a new cultivar of Dahlia hybrid. The new variety is the product of a planned breeding program. The new variety originated as a seedling from the crossing of the unpatented, proprietary seed parent Dahlia ‘268842’ with the unpatented, proprietary pollen parent referred to as Dahlia ‘268857’. The crossing was made by the inventor in his research greenhouse in Mariahout, the Netherlands during July of 2006.

The new variety was first selected by the inventor, Henry Lommerse, a citizen of Netherlands, in July of 2007 at the research greenhouse in Mariahout, the Netherlands. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘LODABALVIO’, assessing stability of the unique characteristics of this variety.

Asexual reproduction of the new cultivar ‘LODABALVIO’ was first performed at a commercial laboratory in the Netherlands by tissue culture in October of 2008. Access to all plants was restricted, as plants were kept in a location not open to the public. Through subsequent propagation both by tissue culture and vegetative cuttings, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘LODABALVIO’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘LODABALVIO.’ These characteristics in combination distinguish ‘LODABALVIO’ as a new and distinct Dahlia cultivar:

1. Unique very bright violet flower color.

2. Compact plant growth.

3. Full, dense plants formed by excellent branching.

4. 4. Flowers held above foliage.

PARENT COMPARISON

Plants of the new cultivar ‘LODABALVIO’ are similar to the seed parent, Dahlia ‘268842’ in most horticultural characteristics. However the new variety, ‘LODABALVIO’ differs from ‘268842’ in the following characteristics:

1. Violet flower color compared to the purple flower of the seed parent.

Plants of the new cultivar ‘LODABALVIO’ are similar to the pollen parent, Dahlia ‘268857’ in most horticultural characteristics. However the new variety, ‘LODABALVIO’ differs from ‘268857’ in the following characteristics:

1. Violet flower color compared to the pink flower of the pollen parent.

COMMERCIAL COMPARISON

‘LODABALVIO’ is similar in most horticultural characteristics to the unpatented commercial variety Dahlia ‘AZTEC CHIAPAS’ in most horticultural characteristics. However the new variety, ‘LODABALVIO’ differs from ‘AZTEC CHIAPAS’ in the following characteristics:

1. Flower color is bright violet. Comparator flower color is purple-red.

2. Different flower shape.

3. New variety has a smaller leaf size.

4. New variety has a more compact plant shape.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘LODABALVIO’ grown outdoors in Honselersdijk, the Netherlands. The plant is approximately 14 weeks from rooted cutting in a 3 liter pot. The photograph was taken in July using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘LODABALVIO’ plants grown outdoors in July in Honselersdijk, the Netherlands. The plant is approximately 14 weeks from rooted cutting in a 3 liter pot. Temperatures ranged between −8° C. and 30° C. day and night. No photoperiodic or chemical treatments were given to the plants. During bright Summer conditions, shade was given. Measurements and numerical values represent averages of typical plant types.
